Wolf is one of the unlockable characters in Super Smash Bros. Brawl, using his appearance from Star Fox: Assault and is voiced by Jay Ward. According to Masahiro Sakurai, Wolf was nearly cut from the game due to time constraints. He is both the biggest and heaviest of the Star Fox characters. He is not as fast as Fox and Falco, but his attacks are more powerful. His aerial speed is better than that of Fox's and Falco's. He can be unlocked by having him join the party in The Subspace Emissary, playing 400 Brawl matches, or by clearing Boss Battles with either Fox or Falco, then defeating him on Lylat Cruise.

Though his special moves are based on the basic design of Fox's special moves, they have been altered for Wolf, with new effects for all of them. All his standard moves are different as well. Wolf's neutral special move is the Blaster, though unlike Fox and Falco's the gun has a claw-like extension that damages nearby opponents. His side special is Wolf Flash, which gives Wolf some vertical height and has a meteor smash at the end. His up special is Fire Wolf, in which Wolf instantly charges in the direction held on the control stick, the air surrounding him damaging opponents. His down special is Reflector, which has a different visual effect than the other characters' Reflectors and increases the speed of reflected items and projectiles rather than power. His Final Smash is the Landmaster, his version having more firepower and sports Wolfen coloration.

Wolf also appears in all of the Star Fox character smash taunts on Lylat Cruise.

In the Subspace Emissary, Wolf doesn't play a major role and does not interact with other video game characters, but can join the player's party after beating Tabuu, along with Jigglypuff and Toon Link. The player must enter a special Red Door in The Ruins stage, which will take them to Lylat Cruise. The player sees Wolf flying his Wolfen. He then jumps out of the Wolfen, and lands on the cruise. Wolf strikes a pose and then rushes at the player attacking him or her. The player must then defeat Wolf in a one-life stock battle. After defeat, he joins the party.

A pilot whose real name is Wolf O'Donnell. He leads a group of mercenaries called Star Wolf. He's crossed paths with Fox many times, and each acknowledges the other as a competent rival. Wolf's constant interference with Fox is a result of Wolf's history with Fox's dad, James. Wolf's long history of criminal enterprise has resulted in a large bounty on his head.

Wolf's Final Smash. Wolf analyzed Fox's Landmaster and built his own improved version, which he now calls out and boards. He's increased the output of the onboard generators and upped the vehicle's firepower. However, this has substantially decreased the time the Landmaster can appear on the screen. It sports the same colors as Wolf's Wolfen.

Wolf used to fight in Andross's army, tangling with Star Fox in battle after battle. After Andross's exile, he went his own way and formed a mercenary team called Star Wolf. He and his eternal rival, Fox, have even fought on the same side from time to time...but inevitably, they always meet again as enemies.

"You know you are all like us. Our fates are intertwined. We are destined to meet in battle. After all, what fun is there to be had in peace and quiet? A true warrior can only live in the battlefield!"

"Listen close: I won't let a single one of you leave here alive! And Fox, remember this! I'm the one who's going to take you down!"
